Final specifications for the AMD Radeon RX 6600 XT and RX 6600 are now in sight, with the RX 6600 XT having 2,048 cores and the cut-down RX 6600 having slightly less at 1,792, according to new GPU-Z screenshots based on the Navi23GPU. Importantly, both have 8GB of GDDR6 memory.

This information comes from two screenshots of GPU-Z posted on the technology forum Chiphell (via Videocardz), which lists the specifications of two unreleased RDNA 2 graphics cards, the first with the AMD Radeon RX 6600 XT, listed as 73FF C1, and is built on a Navi 23 GPU. Its 2,048 cores have 32 ROPs and 128 TMUs, accessible via a 128-bit bus and 8GB of GDDR6.

Then there is the RX 6600, with 1,792 cores, 32 ROPs, and only 112 TMUs. This card also has 8 GB of GDDR6 and a 128-bit bus.

Both use the same RDNA 2 architecture that is currently on the RX 6700 XT through the RX 6900 XT.

These two GPUs also recently appeared on the EEC list from ASRock. However, we cannot rule out the possibility that AMD will appear at the virtual E3 with its own stream and announce the two cards there. [But with Nvidia starting to roll out cheaper GPUs with the RTX 3060 12GB and mobile RTX 3050 Ti and RTX 3050, perhaps the pressure for AMD's own RDNA 2 answer is mounting.

By the way, beyond the Navi 23 GPU codenamed Dimgrey Cavefish, another GPU has now been confirmed with a Linux driver codename: Beige Goby (via Phoronix). This chip will most likely be the Navi 24, which is currently quite slim for our gaming tastes, but may still be good news for budget gamers looking for a serious entry-level fix since Polaris.

There is definitely more to come from the RDNA2 architecture, and whatever AMD's track record, it may be where the company will flourish the most. That is, if the global chip shortage doesn't get in the way. It is likely to be plagued by inventory shortages for some time yet. [If AMD's RDNA 2 GPUs start to outperform the ethereal hash rates of the RTX 30 series, demand may eventually be higher. That seems likely, as the RX 6600 XT's reported mining hash rate of 30 MH/s is not noteworthy at this point, but as Nvidia is reportedly cutting its overall gaming card hash rate in half, the RDNA 2 will become more attractive to miners will be.
